MACHINE FOR'QLEANING' CASTINGS.

SPECIFICATION forming part of Letters Patent No. 554,473, dated February 1 1, 1896. Application filed June 20, 1895. SerialHo. 563,397. (No model.) Patented in Germany January 7, 1893,1Io. 71,824.

To'all whom it may concern.-

Be it known that I, HANS BEEG, a subject of the Emperor of Germany, and a resident of Durlach, in the Grand Duchy of Baden, Germany, have invented new and useful Improvements in Machines for Cleaning Castings, (for which I have obtained Letters Patent in Germany, No. 71,824, dated January 7, 1893,) of which the following is a specification.

My invention has reference to a sand-blast apparatus of that class in which the sand is thrown against the casting or other object to be cleaned by a rotating wheel or projector and the usual air-blast dispensed with.

It consists essentially in combining, in a sand-blast apparatus, a projector provided with radial blades and mounted to rotate in a vertical plane, a support for the castings disposed to rotate in a horizontal plane, and a feed for conveying the sand to the projector.

The nature of my said invention-will best be understood when described in connection with the accompanying drawings, in which- Figure 1 representsa vertical section on the line 1 1, Fig. 2, of an apparatus embodying my invention. Fig. 2 is a sectional plan view of v the same. Fig. 3 is a vertical section, on an enlarged scale, taken through the projector and chute. Figs. stand 5 illustrate a modified form for the projector. Fig. 6 is a sec- ".=.tional elevation illustrating a projector provided with blades on both sides.

Similar letters of reference designate corresponding parts throughout the several views of the drawings.

-Referring at present to Figs. 1, 2, and 3 of the drawings, the letter A designates the projector, which is mounted on a horizontal shaft S and has a high speed of rotation imparted thereto through the pulley B mounted on said This projector consists of a circular disk having on one face thereof a s'eriesof radial blades a adapted to receive and dis tribute the sand in a vertical plane. Beneath the projector is arranged a work-support T made in the form of a turn-table mounted to turn in a horizontal plane. In the present vided with'a circular rack t into which meshes a gear 21. mounted on a horizontal shaft provided with a driving pulley or gear 8, The

A. The apparatus is partially iuclosed by stationary casing F, while beneath the worksupport a suitable funnel or conduit G is arranged for returning the sand to the pit.

In Fig. 6 I have shown the projector A provided with radial blades a arranged on both its faces, and the chute D. provided with two discharge-openings or branches d for conveying the sand to the projector.

I In Figs. 4 and 5 I have shown the projector provided with a central inlet-opening for the sand conducted thereto by the conduit D and with a series of radial blades iuclosed by circular heads. The projector is partly surrounded by a curved casing g to effect the project-ion of the sand in the direction indicated by dotted lines in Fig. 4.

It is evident that the several devices for feedingthe sand or other cleaning material to the projector, for holding the castings, and for imparting motion to the several operatingdevices may be modified in many ways. Therefore I do not wish to restrict myself to the precise construction shown, the main features of my invention being the vertical projector provided with lateral blades for directing the cleaning material against-the castings and a rotary support for the castings arranged in a horizontal plane.

What I claim as new isv1. In an apparatus for cleaning castings, the combination of a support for the castings rotating in a horizontal plane, a rotary projector mounted'to rotate in avertical plane,

and provided with lateral blades, and a feed for conveying the sand to the projector, substantially as described.

2. In an apparatus for cleaning castings, the combination of a perforated support for the castings mounted to rotate in ahorizontal plane, 'a rotary'projector mounted in a vertical plane and provided with radial latera1blades,-a conduit for sand opening latthc sand from the pit to the conduit, and a erally to the projector, and means for confunnel or conduit located beneath the support veying sand to the conduit, substantially as for conducting the sand to the pit, snbstandescribed. tially as described. v
